ISRO’s Aditya L1 Mission Collects Science Data, Unraveling Solar Wind and Space Weather Phenomena

ISRO’s Aditya L1 Mission Begins Collecting Science Data

ISRO’s Aditya L1 mission has entered a new phase as it starts collecting scientific data using the Supra Thermal and Energetic Particle Spectrometer (STEPS) instrument. This instrument will provide insights into the origin, acceleration, and anisotropy of solar wind and space weather phenomena.

Key Takeaways:

The Aditya L1 spacecraft is now in a heavily elliptical orbit of 256 km x 1,21,973 km.

STEPS was activated when the spacecraft was 50,000 km away from Earth, which is more than eight times the Earth’s radius.

STEPS comprises six sensors to measure supra-thermal and energetic ions, aiding scientists in understanding the particles surrounding the Earth.

The data collected by STEPS will persist throughout the mission and will continue once the spacecraft is in its intended orbit.

Unraveling the Mysteries of Solar Wind and Space Weather

STEPS, designed by the Physical Research Laboratory (PRL) in collaboration with the Space Application Centre (SAC), plays a crucial role in unraveling the mysteries of solar wind and space weather. The instrument consists of six sensors that measure supra-thermal and energetic ions in different directions.

By analyzing the data collected by STEPS, scientists will gain a better understanding of the nature and behavior of particles within the Earth’s magnetic field. This knowledge will contribute to advancements in space weather forecasting and protection of space-based assets.

Aditya L1 Mission: Exploring the Sun

Aditya L1, India’s maiden mission to study the sun, was launched on September 2 using a Polar Satellite Launch Vehicle (PSLV-C57). The spacecraft is currently in a lower orbit and will be directed towards the Lagrange point, also known as L1. This strategic position will enable Aditya L1 to collect vital data for a comprehensive understanding of the sun’s dynamics.

The Aditya L1 mission marks another milestone in ISRO’s pursuit of scientific exploration and technological advancements. With the commencement of data collection by STEPS, researchers are eager to delve deeper into the mysteries of solar wind and space weather.
